Size: The Javan rhino is a smaller and lighter relative of the greater one-horned rhino. It stands at 1.4 to 1.7 metres tall at the shoulder. There is not much difference in size between the males and females, and from information gathered in Ujung Kulon and from museum skeletons, there is a possibility that females are slightly bigger.
Weight: Javan rhinos are comparable in size to the African black rhino, though only a few animals have actually been weighed. They typically range between 900 and 2,300 kg.
Lifespan: Javan rhinos are estimated to live an average of 35 to 40 years in the wild.
Skin colour: Javan rhinos have grey or grey-brown skin, almost black when wet, with pink colouring in the folds.
